To all whom t may concern:

Be it known that I, WALTER M. INGR'AM, a citizen of the United States of America, residing in Baltimore, State of Maryland, have invented certain new and use ful Improvements in Seal-Making Machines, of which the following is a specification.

The machine which is the subject of this application is for use in the manufacture of bags, wrappers or seals, particularly adapted for wrapping and closing or sealing bottles. My invention has been developed in connection with the wrapping of milk bottles but it is capable of general application.

The machine in the preferred form illustrated operates by cutting from a web, blanks of twice the length of the seals or bags to be produced, folding them about a transverse central line, turning the edges of one-half over the edges of the other half and pasting them. The bags or seals in the preferred form are tapered or reduced at the closed end and of angle to suit the bottle.

Other machines having as a principal function the manufacture of similar seals or bags have been produced. The object of the present invention is the development of a machine for the' manufacture of the seals described which is more compact, cheaper in construction, and quicker in operation than the machines of this general type heretofore produced.

In the accompanying drawings I have illustrated a machine embodying my invention in the preferred form.

ig. 15 is a plan of a blank and may be taken as a development of the cutting edges of the cutter rollers.

Referrin to the drawings by numerals, there is a rame 1 upon which is supported preferably at the lower central portion, a roll of paper 2 on a suitable roller 3 having journals 4 in suitable bearings 5 in the machine frame. The web of aper 6 is drawn from the roll 2 over a suitable guide roller 7 whence it is led directly into the bite of the take-off and printing rollers 8 and 9, the latter being in the present instance provided with type 10 by means of which the web from which the seals are to be cut is inscribed with any desired marking. The type 10 is inked by a suitable inkin roller 11 which receives its supply of ink rom an ink-carrying roller 12 dipping in an ink reservoir 13.

The machine is driven by abelt 14 which runs over a pulley 15 on a shaft 16 which latter shaft carries a toothed gear 17 meshing with a toothed gear V18-on a shaft 19 of the roller 8 which shaft in turn carries a toothed ear 20 meshing with a toothed gear 21 on a s aft 22 of the roller 9. This toothed gear 21 also meshes with a toothed gear 24 on the shaft 25 of the inking roller 11. This gear 24 in turn meshes with a gear 28 on the shaft 29 of the ink-carrying roller 12. rlhe rollers 8, 9, 11 and 12 being each fast on its shaft are thus driven in accordance with the functions stated.

The shafts 25 and 29 of the rollers 11 and 12 are journaled -in an arm 32 of the frame 1 which is of the cantaliver type, i. e., joined to the frame at one end only so that it is slightly exible, the outer end 33 being connected to a portion of the frame above by a bolt 34, the tension and compression in the bolt being adjusted by nuts 35 and 36` respectively, providing a convenient regulation of the contact between the rollers 9 and 11. Adjustment of the contat between the rollers 11 and12 is provided by means of an eccentric 37 on the shaft 35 controlled by a segment 38 having an arcuate slot 39 engaged by a bolt 40 in the bracket 32. The adjustment of the grip of the printing or takeofil rollers 8 and 9 is accomplished by means of an eccentric 41 on the shaft 22, the eccentric being controlled by a se ent 42 having an arcuate slot 43 engaged y a bolt 44 seated in the machine frame.

From the grip of the rollers 8, 9, the paper web is led over the top surface of the shaft 45 and then clockwise about the rearmost cutting roller 51. The coperating cutting rollers consist of a front roller 52 and the rear roller 51.

It will be noted that the rollers 51 and 52 are in effect an inside and outside cylindrical die respectively, that is, the roller 51 has a cutting edge 53 in the form of a blank and the roller 52 has oppositely disposed cutting edges 54 of the same form or rather of the same outline which lit over or receive the cutting edges 53 between them. One die or cutting edge 53 rolls into the other die or cutting edge 54 with a shearing actlon, cutting a blank of the desired form from the web as it is passed between the rollers.

As has already been explained, the blanks are twice the length of the finished seals or bags, being folded upon a transverse central line as hereinafter described, the edges of one-half being turned over the edges of the other half so that the dies or rather the cutting edges, in their outline correspond to a figure similar to the blank which, divided on a line corresponding to the transverse central fold of the blank, consists of two separate sections similar except that the width of one exceeds the width of the other by a narrow margin corresponding` to the flap on the large half of the blank which is paste-coated and folded over the edge portion of' the smaller half of the blank. This relation of the two sections has a bearing on the operation of the machine as hereinafter described.

As has been stated, the rear cutting roller or inner die 51 fits inside the cutting surfaces of the front cuttin roller or outer die 52. Both the rollers 0r gies for purposes of construction are made in parts. The roller 52 consists of four parts, 55 at one end carrying one cutting edge, 56 at the other end carrying the other cutting edge, and 57 and 58 on each side of the center forming the detogether by means of bolts 65 and fastened to the shaft by pins 66. The cutting edges 54 of the front cutting roller 52 are add justed by drawing them together against the cuttlng edges of the roller 51 by means of the bolt or lag screw 59 bearing against the outer section 56. The screw 59 is seated in the gear 62 which is secured to the shaft 68 of the front cutting roller, adjustment being accomplished by drawing the edges together between this bolt and the disk 63 pinned on the shaft and serving as a stop or abutment against which one-half 55 of the front cutting roller or die rests. It will be understood that there is normally sufficient play between the sections 55 and 57 and 56 and 58, 55 and 56 being mounted to slide along the shaft, to permit adjustment of the cutting edges in this way by taking up part of the play, the said cutting edges being spaced by the inner cutting edges 53 with which t ey are in contact.

The c utting roller 51 has its cutting edge 53 formlng the internal cutting die arranged to correspond precisely with and fit into the cuttlng edge 54 of the forward cutting roller or external die 52. This rear cutting roller 51 1s made in two parts 87 and 88 pinned or otherwlse rigidly secured to the shaft 16 and preferably spaced by stops 89. Inside the cutting edges, the surface of the roller 51 is level with these cutting edges and serves to contact with the rubber facing 57 of the roller 52 and grip the web and blank as it passes through.

Angular adjustment of the cutter sections .55 1s accomplished as follows: The disk 63 1s secured to the shaft and the section 55 whlch is otherwise free to rotate' on the shaft, is secured to this disk by means of a bolt 69 seated in the cutter section and passing through an arcuate slot 64 in the disk. I also preferably provide the disk and cutter with a scale or vernier 70 so that the angular position of the cutter may be adjusted and determined, the bolt 69 belng loosened, the cutter rotated to the desired position as indicated by the scale, and then made rigid by tightening the bolt. Adjustment of the other cutter section 56 is made by means of set screws 71, 72 seated in lugs 73 in the face of the gear. These set screws bear against a in 74 which is between the set screws and) extends parallel to the axis of the rollers, passing through .a slot in the gear 62 and being seated in and rigidly secured to the cutter section 56. The manner of obtainin this angular adjustment is apparent. t consists in loosening one set screw and tightening the other de pending upon the direction of the angular adjustment desired. The grip of' the cutter rollers is adjusted by a bolt 112 drawing together the two upright arms 113 and '114 on which the rollers are mounted. A

As the forward end of the blank, which is the larger end, protrudes from the rollers, it comes in contact with a stationary stop or shield 75 by which it is deflected as shown in Fig. 1, in which position it bends forward and downward by ravity resting on a support 76 provided or this purpose.

Coperating with the support 76 and the shield 75 is the folder 78. This includes an arcuate plate or folder blade 79, or rather two such plates spaced apart to admit the cutter as hereinafter described. These plates pass between the cutting rollers 51, 52 near the center whereby they avoid the gripping surfaces 57. At the lower end these plates are secured t0 a cross-bar 81 on radial arms 8O loose on the shaft 16, the arm 80 on one side being secured to the boss of a segmental gear 82 which meshes with and is driven by a segmental gear 83 carried by the anged member 63 pinned to the shaft 68. The segmental gears drive the folder during the working stroke as hereinafter described, being returned to initial position by means of a spring 84. y

Above the roller 51 on the shaft 90 is a folder roller 91 shown as made in two sections 92, 93, preferablyspaced as shown, each section being pinned or otherwise rigidly secured to the shaft. The surface of this folder roller is adapted to run in rolling contact with the surface of the cutter roller 51 between the cutting edges. It is also provided with a substantially radial or slightly inclined flange or rib 96 having rounded non-cutting edges of outline to conform to and take over the lateral edges of the smaller cutting section of the inside cutting roller or die 51. The contact of these flanges with the cutting edges is not quite as close as that of the cutting edges 52 with the same cutting edges of the roller 51, the

object ofthe flange or rib 96 bein to fold or crease the edges of the larger ha f of the blank forming iiaps to be turned over the edges of the smaller half of the blank, as hereinafter described. To this end, the roller 91 is driven rotatively by the toothed gear 97 on the shaft 90, meshing with a gear 98 on the shaft 16.

Referring now to Fig. 1, we have a side view of the front or `outside die or cutting roller'52, the rear or inside die or cutting roller 51, the front folding roller 91, shield 75, the blank support 76, and the oscillating folder blade 7 8. When the blank. which in the form of the machine illustrated is cut .large end first and of course feeds in the same relation, issues from the grip of the cutter rollers 51 and 52, it hangs or bends forward over the support 76 as illustrated f tion, i. e., at the end of thewstroke, begm to move upward in right-handed rotation about the shaft 16, the beginning of the stroke of the .folder blades being preferably simul-` taneous with the passing of the center of the blank by the' end of the `folder blade in its lower or n ormal position and with the cuttmg of this part of the blank. The blades make their upward oroperative stroke at a speed substantially equal to the surface,

speed of the rollers 51 and 52, it being understood that the paper at this time is led over the surface of the roller 51 and between this roller and the folder blade 78. As the blank passes upward from the grip of the rollers 51 and 52, instead ofbeing strlpped from the rollers and led upward over the support 7 6, as is the forward end of the blank, the central portion of the blank 1s caught by the blade 78 and carried upward wlth and on the corresponding point of the roller 51 until it enters between and 1s grlpped by the rollers 91 and 51. At this tlme the forward end is still on the support 76. The central portion of the blank thus doubled back over the folder blade is folded -on a line transverse to the length of the blank and as it enters the grip of the rollers 91 and 51, it is duly pressed forming a transverse crease. The blank thus doubled is carried through the rollers, the blade assoon as 1t 1s released by the segments being retracted by the spring 84. During this operation, the front end of the blank' is drawn over the su port 76 and around the edge of the shield 5, beingl given a tension tp ecrrespond to the tension of the rollers 51 and 52 by means of the support 76 which at this time is pressed against the shield, ,75."lhis` effect is intermittent being` acconplished only when the doubled blank is passlng into the grip of the rollers 91 and 51. It is produced by means ofa cam 102 engaging a roller 103 on a lever 104, intermediatelypivoted on the machine frame, the remote arm 106 of the lever hanging below the pivot being connected by a spring 107 with a suitable point on the frame, the tension of the spring having the effect of keeping the roller in contact with the cam by means of a connecting rod 110. The arm 106 transmits the motion ofthe cam to a bell crank 108 pivoted on the shaft 109 seated in the frame 1. The other arm of the bell crank 11 carries the support 76 which is by the action of the cam and levers described caused to rock into contact with the guide at suitable intervals to put the necessary tension on the forlfl ward end 100 of the blank during' the time when the blank intermediately folded is passing between the rollers 51 and 91.

Durlng the passage of the doubled blank between these rollers 51 and 91, the ange 96 on the last named roller engages the overhanging edges or flaps of the large half of the blank, folding them downward and ast the corresponding edges of the small lialf of the blank.

Fig. 15 is a plan of the blank or a development of the cuttingv edges of either catting roller. In this blank or develo ment of the cutting edges, it will be note that there is at the center of each lateral edge, z'. e., near the narrowest point a triangle 150, 151, 152 dened by the outer edge of the fla the crease 151, 152 in alinement with t e edge of the smaller half of the l blank and the crease 152, 150 in alinement with the transverse fold 153 about which the blank is doubled. The lines 154 are the creases upon which the flaps 155 are turned about the edges of the smaller half of the blank 156. The triangles 157 at the time of folding the blank are first turned about the line 150, 152, each of which is a continuation of the line 153. Then when the flaps 155 are turned down by the action of the creaser, the triangles 157 are completed by the formation of the creases 151, 152 at the time in coincidence with or overlying the'creases 154. As both the cutting edges 53 and 54 conform to the outline of the blank, and creases 154 and 151, 152 are formed by the coperation of the creasing roller and the small half or lobe of the cuttin member of the internal cutting die 51, it 1s apparent that in order to form this crease the outline of the internal cutting die must be changed between the cutting and the creasing operation. This is accomplished by making the triangles 157 separate from the rest of the die and giving them an in and out motion relatively to the roller at each revolution causing them to be in the cutting or outermost position during the cutting operation and withdrawn durin the creasing operation. This is accomplished by the mechanism illustrated in connection w1th the roller 51 in Figs. 13 and 14, consistin of a stationary cam160, a sliding meml er 161 mounted in the roller 51 to slide radially thereon, and a follower 162 thereon engaging the cam 160. The sliding member 161 carries at its end a triangular portion 150, 151, 152 having a cutting edge 150, 151. In the preferred form of the invention,l the cutting rollers are made of cast iron and the cutting edges are of tool steel strips or bands 163 on which the cutting edge is formed. This band overlies the sliding member 161 adjacent the triangular portion 150, 151, 152 and the parts are so proportioned that it serves as 4and are unsupported at the forward ends where the roller 91 is journaled at 117. This arm 116 thus possesses a considerable amount of resiliency which is taken advantage of in the adjustment of the grip. These rods 115 are passed through the arms 116 and a corresponding rigid portion of the frame 118. The rods 115 are threaded at each end and have at each end nuts. 119 and 120 on each side of the portion of the frame in which they are seated so that the adjustment by tightening and loosening the nuts in an obvious manneris had, setting up tension in the rod or releasing it, drawing the rollers together or moving, them apart.

The cutting rollers 51 and 52, or more correctly the cutting edges thereof, are arranged to cut one blank at each revolution. In the preferred form, the blank is just long enough to encircle the roller, that is, there is one transverse cutting edge parallel to the axis of the roller by means of which the ends of the blanks are formed or cut. This transverse cutting edge 122 on each roller is omitted or cut away centrally at 123 so that the blanks are not completely cut or severed from the material when released from the cutter rollers. A tab is left which connects the blank in the grip of the folder or creasing roller 91 and the rear cutting roller 51 with the web of material and serves to draw the web forward into the grip of the cutter rollers after the cutting 110 of the preceding blank, and is not severed until this is accomplished.

The cutting of this tab or connecting link is effected by means of an oscillating cutter 125 shown in detail in Fig. 3. This cutter, 11i which is mounted to swing about a stud 126 extending through the machine frame, consists of a blade 127 and a concave cam portion 128. The blade 127 in the normal position or position of rest of the parts is prefl120 erably near, usually a little above, the point of contact of the two cutting rollers. The blade 127 and the cam 128 are centrally placed being between the two sections of the roller 51. The cutter is actuated by a 125 pin Ior follower 129 fixed to the roller 51, the pin or follower engaging and coperating with the cam surface 128 throughout the operative stroke of the cutter. In the normal or position of rest of the parts, the cutlll ayer-aegee ter swings down to its-lowest position, the cam 128 resting on the shaft 16. As the pin 129 swings upward from its lower central position, it comes in contact with the cara and swings thecutting edge 127 forward and'iipward causing`it to engage and sever the tab connecting the blank just out from the web after the latter has been drawn into the grip of the rollers. It will be understood that during this operation, the pin 129 follows the concave cam surface 128 from the present position of the pin as illustrated at one end of the cam surface to the sharp bend 130 where the .two portions 131 and 132 meet. As the operation of cutting is completed, the pin 129 passes the curve 130 and engages the surface 132. While contact with the curve 131 serves to lift the cutter, the contact of the pin with the curve 132 serves to return the cutter, z" e., swing it downward into. original position where it rests on the shaft 16. This motion is ofcourse the result of the combination of the curve of the cam with the circular path followed by the pin 129 and the .rotation of the cutting roller 52. It constitutes the cutting stroke and the withdrawal therefrom. The tab connectin the blanks is narrower than the opening` etween the sections of the cutter roller 5l, see Fig. 15, and overlies this opening. lThe blade 127 is of suitable width and passes through this openin frtgiin the web the blank which has just passed the grip of the cutter rollers. As the blank thus severed from the web and creased as to its flaps emerges from the grip of the rollers 51 and 91, it enters the ways 134 in alinement with the horizontal tangent plane at the point of contact of these two rollers. These ways 134, which are composed of two Hat plates or strips placed horizontally one over the other and spaced apart to admit the ba or seals, are slightly less than the width o the latter and open at the edges. Spaced back from the grip of the folder roller 91 by substantially the length of the finished seals are paste rollers 136. workin in a paste pot 147 and engaging the blank from beneath on either side of the ways. The periphery of these rollers is of if-'shaped cross-section and each is mounted on a U-shaped bracket or arm 137 pivoted intermediately in the machine frame at 138. The bearin of the roller is at one end of the U and t e other end is formed into a cam follower 139 encani surface 140 on a roller 141 @ging a on the shaft 142, driven b the ear 143 from the gear 17 on the sha 16. his cam or cam member 140, which has duplicate cam paths to engage both of the arms 137 so as to actuate both of the paste rollers 136, has an outline corresponding to the outline of the seal so as to move the rollers at each stroke of the cutter and seversA laterally and cause them to follow the configuration of the edge flap. Tt will also be noted that the rollers 136 havin the V- sl'iaped periphery are tipped with t eir axes at an angle of a proximately 60 so that one face of the V ies in a vertical lane and the other in a horizontal plane. he roller 141 in addition to the cam 140 includes a raised portion 144 extendin around aproximately two-thirds of the periphery. his coperates with a small roller 146;

both rollers operate in slots in the ways to grip the blank and` draw it forward at the time when the paste rollers are spaced to engage the flaps at the corresponding end, in this case the closed end or bottom of the bag or seal. Tt will be noted that vroller 141 is, as shown,cut away at the center of its peripheral surface forming a roove 141 which receives the to way 134. he bottom way is cut away at tA e section at this point to provide for the side motion of the paster rollers, so that they can follow the edges of the flaps. The roller v141 also carries a radial ange or-rib 145 shaped to the periphery of the finished seal. -This coperates with the paste rollers engaging the turned flaps `from without and supporting them while the vertical paste roller en ages them from within, the other paste ro ler engaging the adjacent edge surface of the other half of the blank so that the two surfaces. z'. e., the Hap and the adjacent portion ofv the small half of the-blank, which are to be brought into contact on the nishing of the seal or bag, are paste-coated simultaneously.

As the blanks are fed from the grip of the creasing or folder roller 91 and the rear cutting roller 5l, they are released when the closed ends reach the gripping point of the roller 141 with the small roller 146. On account of the fact that the raised portion 144 which forms one element of the gripping surface is discontinued for a considerable portion of the circumference, the bag or seal stops at this point until the paste rollers reach the operative position. Then the bag is fed forward, the flaps which are already creased being turned to vertical position by the flange or rib 145. This flap is engaged from within by the vertical surface of the paste roller and the portion of the smaller half of the blank which is to be engaged by the flap engaged by the horizontal face of the paste roller. When the blank, which is at the saine time guided by the ways, thus folded and paste-coated as to its edges, emerges from the grip of the rollers 141 and 146, it enters a static or tubular folder member 148 wherein ythe paste-coated iiaps of the larger half of the blank are turned flat against the paste-coated edges of the small half of the blank.

This static or tubular folder 148 includes two converging guides 166 adapted to envare of half circular cross-section, z'. e., tubes lane of the axis. Just over the at plates 167 ada ted to enter cut on the tubes are the fold and define it as to t e initial ex tremity and over these is the top plate of the ways 134, lthe same beingremove'd in the Fig. 10 referred to. The ottom plate 1n the way is indicated in this figure by reference character 168. This terminates at 169 and the places of the bottom plate is su plied by a bottom folder late 170 which 1s' flat as to its rear surface 1 1 and incllned as to its forward or receiving end 172. There is also a side guide 173 at this point.

Referring to the develo ment of the blank, it will be noted that in t e form shown, the iiap 155 makes a shoulder or turn forming a shoulder 158 so that in the initial folding operation, the fold would terminate near this point by reaching the edge of the paper. To turn the edges ofthe paper at 158, I provide moving folders 174 in the form of plates having inclined edges 175. Each of these plates has a follower 176 secured'. thereto and slotted to engage the edge f a guide plate 177 having an overhanging portion or bracket 178 through which is assed a bolt 179 with lock nuts 180 outsi e the bracket, the bolt being seated at its other end in the follower 176 and serving as means for limiting the inward motion of the followers. These and the folders are drawn in by the springs 182 engaging the sleeves 183 sliding on a transverse rod 184, each sleeve being secured to the finger 174 by means of a web 181. These folder lingers are controlled by cams 185 on the shaft 186 driven by a gear 187 from the gear 143 which is on and drives the shaft 142, thesame being in turn driven from the gear 17 on the shaft 16. The cam 185 is formed of a cylindrical member having roller surfaces 188 to coperate with idler rollers 189 which rest on the paper from above and serve to roll the aps in their folded position, it being understood that after the shoulders 158 are turned by the folder fingers, the drawingof the flap over the plate 171 serves to turn these edges, the same being partly determined as to their position by the guides or stop surfaces 190 upon the fingers, and it is after emerging from the grip of this plate that the folded edges are engaged b the rollers 188 and 189 as already describe from which point they continue a short distance through the ides and are delivered on to the conveyer be t 191.

A transverse plate 195 supports the ide plate 177, the ways 134 at this point all meagre? folder 170. ,At its ends, this plate 19,5 is mounted on vertical bolts or studs 196 seated in the frame, the ends ofthe plate being apertured to slideup and down on the bolts. Spiral springs 197 encircling the bolts and restin on the frame support the plates from beneat This flexible arrangement permits the guides and folder to yield freely and conform to the osition and contact point of the rollers and coperating parts.

The machine consists of a series of groups of mechanism each 'operating on the web or \upon the'blanks cut from the web successively to produce a single result, z'. e., a product in the lform of seals or bags for covering bottles.V These groups of mechanism are arranged along the path of the web and blanks in the order of their operation. .I

Referring to Fig. 1 which shows the web and the various groups of parts in their operative relation, the web 6 is drawn from the roll 2 whence it passes over the guide 7 into the grip of the printin or take-off rollers 8, 9. The type 10 on t e roller '9, inked by the inking rollers 11, 12, prints any desired legend om the web, ink being supplied to the rollers 11, 12 from the ink pot 13. From the grip of the rollers 8, 9, the paper is led over the shaft or rod 45 into contact with the cutting roller 51 around which it passes clockwise into the grip of the cutting rollers 51 and 52 where the blanks are cut by the coperating action of the cutting edges 53, 54 thereon. The forward end of the out blank is guided upward by the shield `7 5 and bends forward and rests over the .support.76. When the central portion of the blank comes opposite the ends of the folder bladesv7 9, these folder blades which oscillate about the center of the roller 51, swing upward with the blank or rather follow the center of the blank upward, folding it about the edge of the folder -blade and thrusting ythe transverse fold .thus formed into the grip of the rollers 51 and 91. The mechanism is so timed that the blank thus folded, the larger section over the smaller section, overlies the small lobe or section of the outline of the cutter edge on the roller 51. Corresponding to this, there isa flange or rib 96 on the folder roller 91 which serves to turn the overlying edge of the large half of the blank about the cutting edge corresponding to the small half of the blank, and incidentally over the corresponding edge of the small half of the blank. To permit the blank to be thus folded, it is necessary to withdraw two small portions of the cutting edge of the roller 51. These are mounted on triangular portions of the surface of the roller corresponding to the triangles 150, 151, 152 in Fig. 15. This is accomplished by a cam action already described. The blank thus folded then enters the ways 134 where the it rests or dwells until engaged and carried wearer forward by the fragmentar circumferential raised portion ida of the ro 1er 141 coperating with the idler roller 146. When the blank is thus engaged and carried forward, the paster rollers 136 are suitably spaced to contact and coat the surfaces of the flaps 155, already turned up by the action of the roller 91 or the rib thereon. These'paster rollers have on their peripheries two surfaces at right angles so that one surface contacts the flaps 155 from below or within and the other a margin of the small half of the blank to be plete. n the blank at different points in its len h, the

rollers swing laterally to conform to t e out-Y line of the blank, being controlled b cams- 140 acting on the followers 139 on t e c entrally pivoted U-shaped levers 137 which carry the rollers. vIn coating the edges of the blanks, the rollers are pressed laterally by the levers 57 against the flanges 155. rIhis lateral pressure moves each roller up the inclined end of its-lever on which it 1S journaled, causing it to take the position shown in Fig. 5, pressing both surfaces of the roller against the corresponding surfaces of the blank at its folded edge. When the blanks are thus coated as to their flaps and edges, they are carried on, to and through the tubular folding guide 170 which turns the flaps fiat against the edges of the small half of the blank, in which position they are pressed by the action of the idler rollers 189 coperating with the cam roller 188. The operation of the machine is of course continuous and in the form described it is capable of operating at a high speed producing a. product of a uniform and high quality.

The machine vof the invention has the important advantages of compactness,simplic ity 'and economy as to cost of construction as well as speed of operation and low cost of attendance.
